Hi: I had the same problem. Take a look to your alert_$ORACLE_SID.log in $ORACLE_BASE/admin/$ORACLE_SID/bdump. I suppouse that you will see a message like 'WARNING: EINVAL creating segment of size <Hexa number>". This is related to the SHMMAX kernel parameters. Do you have 128 Mb of RAM? This problem only appeared me when installed ORacle 8i in my laptop, that have 128MB, with servers this problem not exist I think that SHMMAX can be changed in /etc/sysctl.conf. Take a look to the shm values neede by ORacle 8i ( i don't remember it now, but you will get it asking google ) Edit /etc/sysctl.conf and search for kernel.shmmax entry. Comment (#) this line and create another one with kernel.shmmax=value_needed. Another thing. Use dbassist to create a set of database creation scripts and execute them manually. Dbassist in 8.1.7 is buggy. Don't forget to apply patches after install the software and before database creation. At least the first patch can be obtained here http://downoload.oracle.com/otn/linux/oracle8i/glibc-2.1.3-stubs.tar.gz HTH Regards David Ballester Marko Asplund <aspa@kronodoc.fi>@redhat.com con fecha 26/02/2003 09:03:33 a.m. Por favor, responda a psyche-list@redhat.com Enviado por: psyche-list-admin@redhat.com Destinatarios: psyche-list@redhat.com CC: Asunto: Oracle8i installation problems i'm having problems installing Oracle8i (r3) on a Red Hat 8.0 machine. the installation of the software itself goes fine but database creation fails. i've tried creating the database both during and after installation using the Oracle Database Configuration Assistant (dbassist) but it fails with the following error message: 'ORA-12547: TNS: lost contact'. i've also tried creating database creation scripts using dbassist and running these scripts manually. the scripts use svrmgrl which fails to connect to the database and prints the following error message: 'ORA-03113: end-of-file on communication channel'. any ideas on how to fix this problem? i have installed Oracle8i on a Red Hat 7.3 machine where it runs fine. best regards, -- aspa http://www.kronodoc.fi/ -- Psyche-list mailing list Psyche-list@redhat.com https://listman.redhat.com/mailman/listinfo/psyche-list -- Psyche-list mailing list Psyche-list@redhat.com https://listman.redhat.com/mailman/listinfo/psyche-list
